Please let trados studio be able to handle the sdlxliff documents created by previous version of trados studio.

We received some documents created by other partners. After we finished the translation, we try to generate the target translation, but we received error report like this and can not continue the translation work.

Besides, when we try to verify the document with the "verify" in "review" of trados stuido, we received error report like this.

We are frustrated about this. Could you please tell me what is the cause for this unexpected error? Can you fix the bugs?

Besides, in some articles,  I found that this might be due to the sdlxliff documents created by early or previous version of trados studio. However, It is necessary for the latest version of trados studio can handle all the sdlxliff documents created by early or previous version of trados studio such as trados studio 2015 or earlier version.

Just imagine, if a translation company working with trados studio has survive for more than 10 years, they even can not handle the previous sdlxliff documents created in the past with different versions of trados studio.

Even today, the Microsoft office 365 with the latest version or all the Microsoft office version can handle the old version of word 2003 document. Will each version of trados studios be useful for only several years?
